Combretum, the bushwillows or combretums, make up the type genus of the family Combretaceae. The genus comprises about 272 species of trees and shrubs, most of which are native to tropical and southern Africa, about 5 to Madagascar, but there are others that are native to tropical Asia, New Guinea and the Bismarck Archipelago, Australia, and tropical America.
Around 17 species in the genus Quisqualis are very similar to Combretum and are now classified as species of the genus.

A samara (/səˈmɑːrə/, UK also: /ˈsæmərə/) is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit, and is indehiscent (not opening along a seam). The shape of a samara enables the wind to carry the seed further away from the tree than regular seeds would go, and is thus a form of anemochory.
In some cases the seed is in the centre of the wing, as in the elms (genus Ulmus), the hoptree (Ptelea trifoliata), and the bushwillows (genus Combretum). In other cases the seed is on one side, with the wing extending to the other side, making the seed autorotate as it falls, as in the maples (genus Acer) and ash trees (genus Fraxinus).
Tarangire National Park is a national park in Tanzania's Manyara Region. The name of the park originates from the Tarangire River that crosses the park. The Tarangire River is the primary source of fresh water for wild animals in the Tarangire Ecosystem during the annual dry season. The Tarangire Ecosystem is defined by the long-distance migration of wildebeest and zebras. During the dry season thousands of animals concentrate in Tarangire National Park from the surrounding wet-season dispersal and calving areas.
It covers an area of approximately 2,850 km (1,100 sq mi). The landscape is composed of granitic ridges, river valley, and swamps. Vegetation is a mix of Acacia woodland, Combretum woodland, seasonally flooded grassland, and Adansonia trees.
The Combretaceae, often called the white mangrove family, are a family of flowering plants in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in 10 genera. The family includes the leadwood tree, Combretum imberbe. Three genera, Conocarpus, Laguncularia, and Lumnitzera, grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from Terminalia ivorensis. The commonly cultivated Quisqualis indica (as well as the entire former genus Quisqualis) is now placed in the genus Combretum. Many plants in the former Quisqualis genus contain quisqualic acid, a potent nerve toxin.
